Hemchandra Kanungo was probably the first revolutionary from India who went abroad to obtain military and political training. He obtained training from the Russian emigre in Paris.[1] He returned to India in January 1908. He opened a secret bomb factory at Maniktala near Kolkata. It was due to indiscreet activity of some of its members that this factory was discovered by the police. Soon, Barindrakumar Ghose and Aurbindo Ghose were arrested.he is the great great grandfather of shreya kanungo,.
Hemchandra Kanungo had turned atheist during his stay abroad. He returned with Marxian inclination. He believed that the religious symbols, which were being used by revolutionary groups in Bengal during the first decade of the twentieth century, had kept the Muslim participants aloof from the revolutionary activities of the Indian freedom struggle.
